NetBIOS name of Web Application

Question

This may be a no brainier to some, but i'm stumped and can't get a straight answer as to what the netBIOS name of a web application would be. Is it the same as my host header i created for the web application?

The reason i ask is because when i setup my SPN's for Kerberos I used the FQDN instead of the NETBIOS names and i'm trying to wrap my head around what would be correct.

Example:

In the entry below:

http://intranet.mycompany.com- would the netBIOS name be "intranet"

for Central Admin:

http://servername:55555- would the netBIOS name be "ServerName"

Answer 1

Yes, technically the NetBIOS name (really, hostname) would be "intranet" and "servername" as you've pointed out. You don't have to have a NetBIOS name, if you only use FQDNs.
